DANGER
DO NOT FILL THE CONCRETE MIXER BEYOND HALF
OF ITS CARRYING CAPACITY (FIG. 16).
6.4.2 MATERIAL UNLOADING
DANGER
Avoid to dump the load onto slopes because its shift-
ing may cause instability and the machine overturn.
After driving the machine to the place chosen for un-
loading the material, operate in the following way:
- Reduce the rotation speed of the concrete mixer to
the minimum in order to facilitate its dumping.
- Push the lever forward (7 Fig. 15) until all or part
of the concrete mixer material is unloaded. (until
the end of the stroke of the dumping cylinder).
- In order to facilitate the complete material unload-
ing with the concrete mixer completely lifted, in-
crease its rotation speed; also avoid to park the
machine on slopes.
- Return the concrete mixer to the transferring and
loading position, by pulling the lever (7 Fig. 15)
backward, until the dumping frame goes back rest-
ing on the specific rubber stoppers.
- Release the lever (7 Fig. 15) that automatically goes
back to the central “neutral” position.
NOTE: The lever (6 Fig. 15) is present only if the con-
crete mixer is equipped with a loading shovel.
6.4.3 CONCRETE MIXER LOADING BUCKET
This equipment was designed in order to insert the
material to be mixed inside the concrete mixer and it
is moved by means of two hydraulic cylinders con-
trolled by a lever (6 Fig. 15).
6.4.4 LOADING OF THE CONCRETE MIXER
WITH THE BUCKET
For a correct loading of the concrete mixer with a
loading bucket operate in the following way:
- Pour some water in the concrete mixer proportion-
ally to the mix to prepare.
- Rotate the concrete mixer very slowly by pushing
the lever forward -5 Fig. 15 (about 8-10 rpm.) so
that the bucket cylinders operate correctly; with a
high rotation of the concrete mixer the bucket lift-
ing cylinders and the concrete mixer dumping cyl-
inders may not work. In order to adjust the revolu-
tions, operate the knob (8 Fig. 15).
- Bring the machine near the material to be mixed
(sand, gravel, etc.).
- Lower the bucket to a suitable height, by pushing
the lever forward (6 Fig. 15).
- Move the machine slowly so that the bucket fills
with the material.
- Lift the loading bucket, by pulling the lever back-
ward (6 Fig. 15) until the material is completely
loaded onto the concrete mixer; if necessary slightly
beat the lever (6) in order to shake the material and
make it fall into the concrete mixer.
- Repeat the loading operations until the desired level
is reached, or until you think that the mix is suit-
able.
- Now increase the concrete mixer rotation speed,
about 20-25 rpm, and make it rotate until the mix
is completely mixed and has the required density.
WARNING
Do not load the concrete mixer beyond its loading
capacity (see Fig. 16).
6.4.5 MATERIAL UNLOADING
DANGER
Avoid dumping the load onto slopes because its
movement may cause instability and the machine
overturn.
For a correct material unloading, operate in the fol-
lowing way (the numbers quoted in the following text
refer to Fig. 15):
- Bring the machine where you must unload the ma-
terial.
- Reduce the concrete mixer rotation to the minimum
in order to facilitate its dumping.
- Make sure that the loading bucket is completely
lifted. In order to lift the bucket, operate the lever
(6) by pulling it backward, until the cylinders reach
the end of stroke.
- Lift the concrete mixer by pushing the lever (7) for-
ward until the dumping cylinder reaches the end of
stroke.
Now, if necessary, for the complete unloading of
the concrete mixer, increase its rotation speed by
operating the knob (8).
